What a good sport! These are images from the old, wonderfully homoerotic rituals of crossing the equator, which unfortunately are a thing of the past, even all male ships are a thing of the past. Seems like back then even straight guys were a lot better at gay stuff than gay men are now.
And after the spanking, the simulated sex! And then another spanking...
The paddles were made from firehoses. Anybody ever been spanked with something like that?
From what I've read, in most situations like this, there was a strict rule you couldn't hit anybody anywhere but on the ass, which is obviously absolutely correct. Modern gang initiations often involve punching, etc., and no spanking, which I attribute to homophobia.
